---------------------------
Resolution: Won't Fix
> Java 7 support for commons-scxml2
> ---------------------------------
>
> Key: SCXML-248
> URL: https://issues.apache.org/jira/browse/SCXML-248
> Project: Commons SCXML
> Issue Type: Wish
> Affects Versions: 2.0
> Reporter: Yuriy Flyud
>
> commons-scxml2 project is compiled with Java 8. Attempts to compile sources
> with Java 7 fail because of usage of lambda expressions, etc. The problem
> number two is usage of JDK 8+ Nashorn Script Engine in JSEvaluator that is
> not available in JDK 7 (the one with Rhino). Tests for JSEvaluator fail on
> Java 7.
> The good news is that all the Java 8 specific features are used only in the
> env.groovy package, and Script Engine Replacement issue affects only
> env.javascript package. All the core functionality can work, and actually
> works, with Java 7.
> I propose to extract the core functionlaity from the commons-scxml2 to
> something like commons-scxml2-core, and make it Java 7 compatible.
> There are currently no any known stable SCXML Engine implementations that
> support latest SCXML specification, so disabling the Java 7 compliance
> forbids many developers like me to use it in their products.
> From my side I can propose creating a fork on Git repository for Java 7
> compatible commons-scxml2 project in case you decide to leave everything as
> it is.
